Product Details

The Chauvin Arnoux CA5231 is equipped for carrying out all basic electrical measurements; it can test AC/DC voltage (including LowZ voltage), AC/DC current, resistance and tests continuity and diode. The built-in non-contact voltage detector to verify whether a circuit is live or not (if the screen turns red, there’s voltage present).

The CA5231 maintains its accuracy, even when testing on irregular AC wave-forms. This unit also comes with a selection of additional features including auto or manual range selection, display hold (freezes the current value on the screen) and IP54 protection against dust and water splashes.

Key Features

  • Audible continuity and diode testing
  • AC current testing to 600A (with 1mV/A clamp – sold separately, part number: P01105103Z)
  • Built-in non-contact voltage detector – ideal for verifying if a circuit is live before testing
  • Display hold function – freezes the current value on the screen
  • Powered by standard 9V alkaline batteries
  • IP54 protection rating – protected against dust and water splashes
  • Shockproof casing – ideal for demanding environments
  • Easy test selection using a rotary dial
  • CAT IV 600V and CAT III 600V safety rated
